Effects of Nitrogen Addition on Microbial Carbon Use Efficiency of Soil Aggregates in Abandoned Grassland on the Loess Plateau of China

Forests, 2022
Soil microbial carbon use efficiency (CUE) plays a crucial role in terrestrial C cycling. However, how microbial CUE responds to nitrogen addition and its mechanisms in soil aggregates from abandoned grassland systems remains poorly understood.

Assessing the spatiotemporal dynamics of ecosystem water use efficiency across China and the response to natural and human activities

Ecological Indicators, 2021
In the context of increasing global carbon emissions, and the relative shortage of water resources, research on the relationships between climate change, human activities and the carbon–water coupling response of China's ecosystems is crucial.

Upscaling key ecosystem functions across the conterminous United States by a water-centric ecosystem model [PDF]

, 2011
We developed a water-centric monthly scale simulation model (WaSSI-C) by integrating empirical water and carbon flux measurements from the FLUXNET network and an existing water supply and demand accounting model (WaSSI).

Does Long-Term Elevation of CO2 Concentration Increase Photosynthesis in Forest Floor Vegetation? (Indiana Strawberry in a Maryland Forest). [PDF]

, 1997
As the partial pressure of CO2 (pCO2) in the atmosphere rises, photorespiratory loss of carbon in C3 photosynthesis will diminish and the net efficiency of light-limited photosynthetic carbon uptake should rise.

Estimating ecosystem maximum light use efficiency based on the water use efficiency principle

Environmental Research Letters, 2021
Light use efficiency (LUE) defines the vegetation efficiency of converting radiative energy into biochemical energy through photosynthesis. Estimating the maximum LUE ( ε _max ) is critical yet challenging for quantifying gross primary production (GPP ...

Recent Response of Vegetation Water Use Efficiency to Climate Change in Central Asia

Remote Sensing, 2022
Quantifying the coupled cycles of carbon and water is essential for exploring the response mechanisms of arid zone terrestrial ecosystems and for formulating a sustainable and practical solution to issues caused by climate change.

Increased Interception Induced by Vegetation Restoration Counters Ecosystem Carbon and Water Exchange Efficiency in China

Earth's Future, 2022
Changes in ecosystem water use efficiency (WUE) and evapotranspiration (ET) that are driven by vegetation change can be used as metrics to quantify ecosystem carbon and water exchange. The effect of vegetation on WUE has been explored in the past through

Climate change impacts plant carbon balance, increasing mean future carbon use efficiency but decreasing total forest extent at dry range edges.

Ecology Letters, 2021
Carbon use efficiency (CUE) represents how efficient a plant is at translating carbon gains through gross primary productivity (GPP) into net primary productivity (NPP) after respiratory costs (Ra ).

Evaluation of the potential for carbon sink and association with land occupation

Journal of Water and Climate Change, 2023
Anthropogenic influences on a global scale have caused negative impacts on the environment, among the most prominent being the increase in the concentration of carbon dioxide (CO2).
